coastal refraction — One of the errors in a direction finder resulting from the change in the direction of travel of a radio ground wave as it passes from one medium to another (i.e., from land to sea or from sea to land). Also called land effect, shoreline effect,… … Aviation dictionary

Coastal geography — is the study of the dynamic interface between the ocean and the land, incorporating both the physical geography (i.e coastal geomorphology, geology and oceanography) and the human geography (sociology and history) of the coast. It involves an… … Wikipedia

Refraction — For the property of metals, see refraction (metallurgy). For the magic effect, see David Penn (magician). For the refraction in atmosphere, see Atmospheric refraction. Light on air–plexi surface in this experiment mainly undergoes refraction… … Wikipedia

shoreline effect — The refraction of electromagnetic waves when crossing a land or a water interface (crossing a shoreline). The bending of the radio waves results in errors in the direction finders. The extent of bending depends on the angle with which the radio… … Aviation dictionary
